AGATA光谱仪是高度分段的高纯锗探测器阵列。光谱仪使用脉冲形状分析来跟踪康普顿散射γ射线，以提高核光谱研究的效率。在利物浦大学对同一A型AGATA的两个高纯锗探测器胶囊进行了表征。这项工作将检查两个胶囊的性能的均匀性，包括分辨率和效率的比较以及电荷收集的研究。胶囊的性能表现出良好的一致性，这是必要的γ射线跟踪阵列的有效操作。
The AGATA spectrometer is an array of highly segmented high purity germanium detectors. The spectrometer uses pulse shape analysis in order to track Compton scattered γ-rays to increase the efficiency of nuclear spectroscopy studies. The characterisation of two high purity germanium detector capsules for AGATA of the same A-type has been performed at the University of Liverpool. This work will examine the uniformity of performance of the two capsules, including a comparison of the resolution and efficiency as well as a study of charge collection. The performance of the capsules shows good agreement, which is essential for the efficient operation of the γ-ray tracking array.
